STM32F4 devices have great feature. They can be programed with only USB to UART converter. Each device has bootloader inside, which supports UART programming. This is not very great method for Discovery boards, because they have better and faster solution on board, ST-link. But if you are working own board, then this solution can be quite nice. In this tutorial, I will go through step-by-step how to program device with USB->UART converter. I will use FTDI’s home made converter. This...

BMP180 is a digital pressure sensor, with builtin temperature sensor. Its range is between 300 and 1100 hPa (0.3 to 1.1Bar). In relating to the sea level, this is +9000 to -500 meters. Sensor works with I2C communication at 100kHz. If you want sensor from ebay, here is one link. Sensor is quite bad created, because if you want to read pressure, you first need to read current temperature for pressure calculation. To read temperature you have to wait at least...
